ROLLING THIN FILM OVEN
MAKE DINESH SCIENTIFIC MODEL DS-RTFO-163C
PRODUCT DESCRIPTION
Rolling Thin Film Oven (RTFO) Test measures the effect of heat and air on a moving film of hot mix asphalt binder, simulating short-term aging that occurs during production and paving operations. This is important for investigating and predicting early age HMA pavement behavior and distress.
Rolling Thin-Film Ovens are used to measure the combined effects of heat and air on a thin moving film of semisolid asphaltic materials/ bitumen or bituminous binders simulating the hardening which most bituminous binders undergo during manufacturing and placement.
FEATURES :
- Low on maintenance
- Smooth functioning
- Ease of usage
